TOWNSHEND AUDIO EDCT ISOLDA SPEAKER CABLE: Analysis    

 Jay Fisher 6Moons Review: 
"Woohoo! When the music poured through these British cables, I blurted an involuntary hoot of approval. The Townshend Isolda cables have much of the midrange openness, clarity and easy flow of the Skywire 1400s but with the addition of greater treble sparkle and deep, take-no-prisoners bass. The lowest plucked acoustic bass notes in "The Saga Of Harrison Crabfeathers" on Brian Bromberg’s virtuosic Wood [A440 Records/ART7009] became more articulate, with clearer pitch definition and harmonic overtones than I had previously heard. I was also surprised by the Isoldas’ seemingly higher efficiency."
"If called upon, these cables can convey a huge and realistic soundstage. They are equally big on tone and texture, which is authentic in character. The Townshend Isoldas are killer cables (maybe even giant killers) and represent great value."
The best and, we think, the ideal speaker cable, with the added bonus that, unlike other cables, different lengths sound the same allowing the use of unequal lengths, saving you money and doing away with unsightly bundles.The gold standard! Constructed with a black braid over insulated EDCT copper strips terminated with unique stabilizing RF filters housed in black anodized aluminium boxes at each end. As with all Townshend’s EDCT cables, Isolda speaker cables are subjected to the Enhanced Deep Cryogenic Treatment process, which gives superior performance to regular Deep Cryogenic Treatment.
Piggy-back banana connectors are fitted as standard, but alternative connectors are available.
For biwire, add extra runs of cable.
Wherever electronic signals are transmitted by wire, be it telephone, video, digital data, radio or TV, the impedance (NOT resistance) of the interconnecting cable is ALWAYS matched to either the source or the load to prevent distortion. This rule is almost universally ignored in the case of hi-fi, where the most important link of all is the speaker cable. The result is a grossly mismatched connection, with the mismatch being typically twenty-to-one, as most speakers have a nominal impedance of about eight ohms and typical cables a characteristic impedance between 100 ohms and 400 ohms. No wonder speaker cables sound wrong!
Townshend Audio Isolda Impedance Matched Loudspeaker Cable, which has a characteristic impedance of eight ohms and remedies this.
To achieve an impedance match at such low impedance values the cable must exhibit very low inductance and high capacitance. It is well known that high capacitance can upset some amplifiers, which become unstable. To counteract this, a correctly engineered, inaudible inductor, in parallel with a damping resistor, is inserted in series with each leg of the cable, at the amplifier end, for assured stability. The two inductors also act as a filter to prevent radio frequency interference (RFI), present in abundance at the end of the cable, from passing to the amplifier's circuitry. Further, the very close spacing of the conductors in the cable provides further RF rejection. The result is black silence.

What happens when the cable and speaker impedance is closely matched? The answer is MAGIC! The sound is fast but not bright; it is clear, open, fatigue-free and grain-free. Bass notes are precisely defined, deep and tuneful, with amazing impact. The mid band, especially female vocals and solo instruments, takes on a naturalness never before heard from the reproduced sound. The treble is smooth and fast, with both brilliance and sparkle. But the cables never sound bright, brittle, grainy or spitty. They just sound ‘right’.
These inherent Isolda characteristics are further enhanced by subjecting the copper conductors to EDCT where the copper is slowly cooled to about 190 degrees Celsius, held there for a number of hours, and then gradually returned to room temperature.
EDCT is proven to improve the lattice structure of copper, eliminating small ‘dislocations’ and having an amazing effect on the cable’s final sound. Dynamics are improved, clarity is further enhanced, and the sound takes on a difficult-to-describe but immediately recognisable naturalness that untreated cables cannot match.

Construction of the Isolda Loudspeaker Cable is both attractive and practical. The two flat strip conductors and their very thin, tough polyester insulation are sheathed in a hard-wearing polyester braid, terminated at each end with non-magnetic stainless steel cylinders. These enclose the complex cable transition as well as the inductors at the amplifier end. To complete the cable, flexible, insulated copper wire tails connect to banana, spade, BFA or Speakon connectors.
The strip conductors are arranged to slide over each other through the braid and cylinders to minimise buckling when coiling the cable. It can be laid under the carpet and folded at right angles. However, it must not be trodden upon when on a hard floor or on edge.
Isolda Loudspeaker Cable is sold in pre-terminated lengths. As the cables are impedance matched, the sound does not change with length; therefore, unequal runs may be used for each speaker Bi – or tri-wiring makes a significant improvement. Bi-wiring is implemented by parallel connecting two identical cables. The parallel connections at the amplifier end are by unique ‘piggyback’ banana connectors.

Over the years, Max Townshend produced several YOU TUBE videos: Geometry matters, describing a method of testing speaker cables by measuring their characteristic impedance; he relates this to how they are constructed its geometry. It goes on to show that speaker cables behave as transmission lines. Therefore, for correct (distortion-free) transmission of the audio signal from the power amplifier to the speaker, the cable must match the speaker load impedance. This analysis clearly describes the cause of audible differences between a range of cables, and the examples included demonstrate this effect.
